3. (a) Light vehicles: Regulations Nos. 68, 83, 101, and 103

7. The expert from OICA introduced ECE/TRANS/WP.29/GRPE/2019/8 and GRPE-78-27 clarifying the relationship between approval levels, reference fuels and particulate number limits for positive ignition engines and to modify the calculation formulae for determining evaporative emissions in accordance with changes already agreed in UN GTR No. 19. He stated that GRPE-78-27 superseded GRPE-78-16 and GRPE-78-16 has therefore not been introduced. He stated that some amendments were about harmonizing national legislation and SAE standards. The Chair insisted that ISO or SAE standards should fit the needs of UN Regulations and not that UN Regulations should align with ISO/SAE standards. The representative from the EC opposed to the change on SCR provisions and accepted the other amendments proposed. The representative from the UK and EC sought clarifications on the use of characters to reflect emission levels. The experts from EC and UK proposed minor corrections to ECE/TRANS/WP.29/GRPE/2019/8 and GRPE-78-27 that GRPE adopted as reproduced in Annex IV to the session report.

8. The secretariat introduced GRPE-78-10 correcting omissions in ECE/TRANS/WP.29/2018/148 adopted in the November 2018 session of WP.29. GRPE adopted GRPE-78-10 as reproduced in Annex V to the session report.

9. The expert from EC introduced GRPE-78-22 introducing minor changes to the 06 and 07 series of amendments to UN Regulation No. 83. The representative from OICA agreed to the changes and expressed his wish to have the changes included as soon as possible in UN Regulation No. 83. The experts from EC, UK proposed minor corrections to GRPE-78-22 that GRPE adopted as reproduced in Annex VI to the session report.

10. GRPE requested the secretariat to submit Annexes IV and VI of the report to WP.29 and Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their June 2019 sessions as draft Supplement 13 and 9 to the 06 and 07 series of amendments to UN Regulation No. 83 respectively. GRPE also requested to submit Annex V of the report to WP.29 and AC.1 for consideration and vote at their June 2019 sessions as draft Corrigendum 1 to Supplement 8 to the 07 series of amendments to UN Regulation No. 83.

11. The expert from OICA introduced GRPE-78-20 proposing to amend UN Regulation No.101 to permit the measurement of fuel and energy consumption and CO2 emissions using road loads which are calculated according to the method used in EU correlation. The representative from EC sought clarifications on the use of CO2MPAS for this proposal. The representative from OICA explained that CO2MPAS formula are expected to be used for the calculation of road load coefficients, without using the CO2MPAS software itself. The representative from EC backed the proposal and requested that the EU JRC be involved in developing the working document. The Chair thanked the representative from OICA for initiating this effort and for making the latest legislative provisions available to all Contracting Parties.
